If you want all upper without modifying the existing queries, you create a view. Of course the real table will need to be renamed first if you really want to avoid modifying the code at all (so that the current name in the query is available as the name for the view.) What part of SQL*Server destroys the uppercase-lowercase distinction? In case I ever have to use that database I want to know. That may be even more information content destructive than confusing the zero length string with a NULL value.

As part of porting an Application from SQL*Server to Oracle, when using SQL/PLSQL etc we need to retrieve Data in UPPER Case "Database-wide" irrespective of Case of storage of data within the field of Table/Index. Wish to Avoid specifying UPPER Clause in the where Query. NOTE - Data may be stored in Upper or Lower Case in Different fields of the Table. NOTE - In the Previous T-SQL Code on SQL*Server the UPPER Clause was NOT needed. Is it possible?
